After seeing many Black Swallowtail (Papilio polyxenes) butterflies and little else on the wing for much of the spring, they have dropped off in number as others increase. What have your observations been? I have been surprised at how (relatively) few Eastern Tiger Swallowtails have been in the air except for a week or two in May. The harsh and historically cold winter likely changed the lepidoptera landscape for us more than usual.
